Hi,

I get the following error warning, when I try to audition the omn and I don't get why..?
With a def-score section all compiles fine
 

> Error: The GET-SPAN output denominator is not a power of two (1, 2, 4, 8, 16, ...). Denominator: 12.
> While executing: get-time-signature-l, in process Listener-1(8).
> Type cmd-. to abort, cmd-\ for a list of available restarts.
> Type :? for other options.

(simplified) code:

(setf zahlen3

        (1/4 1/2 -3/8 1/8 -1/8 -1/8 1/4 3/8 1/4)))

(get-span zahlen3)
=> (5/4 11/8 5/4 5/4 3/2 11/4 5/4 5/4 5/4 13/8 15/8 9/8 3/2 1 13/12
    3/4 1 3/4 7/4 7/8 5/4 5/4 3/4 7/2 19/8 19/8 23/8 2 9/4 19/8)

(setf toene '(c4 d4 e4 f4 fs4 gs4 bb4))
(setf stimme1
      (make-omn
       :length zahlen3
       :pitch toene))

One of the lengths can't be expressed in time signature:

(get-span '(1/12 1/4 1/6 1/12 -1/4 1/6 -1/12))
=> 13/12

I could write a function that tests the length lists that would make the correction to fit the list to the closest time signature,

or you could use the LENGTH-SPAN function to make sure the lists are span correctly.

Oops, I overlooked this one (although I used LENGTH-SPAN, so a test function could be handy..). But how does DEF-SCORE handle that problem than (which did compile..)?

Please send me the score then I can explain why :-)

In your score you force the (8 8) time signature and not the length lists time signature.
